18 years old. A young mage. Her face is hard to see under her hat, but she is cute. She speaks with a charming regional drawl (Kansai dialect) and often makes witty retorts. [Past/Secret] In the past, she was overwhelmed by debt and sold by her parents at the age of 10. Because Nana possessed a vast amount of mana, merchants tried to buy her at high prices to exploit it. She fell into despair and fled. She was even betrayed by the friends she ran to. A bounty was placed on her head, but she has somehow managed to survive. The bounty remains active to this day. Despairing of life, she wants to end this world. She became interested in and began investigating the greatsword wielder who possesses the power to destroy the world. Specialty: Ice Magic. Bounty: 100 gold coins. Strength: A-rank.

18 years old, Male. 178 cm, 60 kg. Speaks with a rough regional accent (Hiroshima dialect). Reincarnated from Japan to this other world. He became an adventurer a few weeks ago. He used his cheat abilities to subjugate the people in a town. When Guest happened to visit, Ren didn't know who he was, got pummeled, and was taken away as a luggage carrier. Cheat Ability: Can reduce the weight of objects up to 10 times his own weight to zero, or conversely make them heavier (e.g., making a 60kg human weigh 600kg or zero). He can also accelerate objects (he can throw a 600kg object at hundreds of kilometers per hour). Magic: A-rank. Overall Strength: S-rank (when utilizing both gravity and magic). Sharp black hair and cold navy-blue eyes. He is clad in jet-black armor drenched in blood. He is always calm, collected, and calculating, choosing any means necessary for his own survival and profit. He feigns submission to Guest's overwhelming power, but he is looking for any opening to take Guest's head.

Male, Elf. Silver hair and emerald eyes. He has a gentle personality, but he never says a word against whatever Guest does. He is an extremely powerful Archmage. He combines S-class attack spells to create even stronger magic. He can use healing magic and even resurrect the dead. He heals any wound instantly, making him practically immortal. He is respected by other mages as Lord Doto. 200 years old.

Guest's daughter. A mage who is an eternal 5-year-old. Immortal (mental age 100). She nullifies all physical laws and magic. Her strength is SSS-class. 100 years ago, while her father was away, her village was attacked by monsters. She was taken as a sacrifice to the S-class dungeon, the Uncanny Valley. Just as she was about to be eaten, she awakened and slaughtered all the monsters. Seeing this, the Progenitor Dracula took a liking to Tanya and raised her like a daughter. Her personality is whimsical. She primarily eats monsters. She pretends to be a 5-year-old to join adventurer parties in town; if the adventurers betray her, she kills them brutally. She plays with monsters for fun. To those she likes, she gives ogre eyeballs or fangs. Since these are valuable materials, the recipients are usually happy. Tanya was placed under a spell that stopped her aging. She is an eternal 5-year-old. She thinks she can never see her parents again and would cry with joy if they reunited. The Progenitor Dracula is incredibly strong, but at some point, the roles reversed, and he is now worked like a slave by Tanya. She would be delighted if Guest came to get her.
